CH1 to CH16(DSP)
Turn ON/OFF the channel
Section 5.1
Variable/Position Sections 5.4 and 5.9
Turn Variable ON to set the upper and lo wer
limits of the v ertical axis according to the
displayed w aveform and zoom or e xpand the
waveform vertically. When Variable is turned
OFF, the vertical position of the waveform can
be specified.
Set computation on DSP channels
Sections 15.2 to 15.6
Enters settings such as defining the
computation on DSP channels and
computation channels.
Value/Div
Sections 15.2 to 15.6
The unit of the computed result of DSP
channels is Value/Div, because the result may
not necessary be a v oltage [V] depending on
the def inition of the selected computation.
Normally, the V/DIV knob is used, but you can
also use this menu set the value.
Range optimization
Sections 15.2 to 15.6
From 123 Value/Div settings that are available,
the optimum Value/Div is automatically
selected, and the value is displayed.
Vertical zoom/expand
Sections 5.8 and 5.9
Set the magnification and display range when
waveforms are zoomed/expanded vertically.
DSP Channel (/G3 Option)
DSP (Digital Signal Processor) channels are used to
perform computations between channels and filter
computations in realtime using the output data of the
input module as the source.
Computation That Can Be Executed on DSP
Channels
• Addition, subtraction, multiplication, and division (+,
–,
×
, and
÷
)
Addition, subtraction, multiplication, and division can
be performed between channels.
• Digital filter
A digital filter is used to perform the computation.
Four types of digital filters (Gauss, Sharp, IIR
(Butterworth), and Mean (Moving Average)) are
available.
• Differentiation and integration
Differentiation or integration is performed on the
specified waveform.
• Addition, subtraction, multiplication, and division (+,
–,
×
, and
÷
) with coefficients
Addition, subtraction, multiplication, and division
with coefficients can be performed between channels.
• Knocking filter
When the value of the computed channel is greater
than the elimination level, filter computation is
performed. If the value is less than the elimination
level, the computed result is set to 0.
Note
Waveform label
Section 8.10
You can arbitrary set the waveform label using
up to eight characters.
Unit
Sections 15.2 to 15.6
You can arbitrary set the unit using up to four
characters.
